After 290200@main, some pages that require us to perform a COOP process swap in response to their Cross-Origin-Opener-Policy would not load when going back to them from another page. Example is going to any YouTube.com page, then navigating away (for example to webkit.org) then clicking the back button to navigate back. Fix this by using the synchronous HistoryController API for IPC calls to the UI process in these cases.
